Maxwell White Hunter II (March 11, 1922 – November 10, 2001) was a prominent American aerospace engineer. He worked on the design of the Douglas B-42 and Douglas B-43 bombers, the Honest John, Nike-Ajax, and Nike-Zeus missiles, the Thor IRBM, and on parts of the Strategic Defense Initiative. In later years he worked on space-launch vehicles and was a proponent of Single-stage-to-orbit (SSTO) designs. He was honored in 1995 by the National Space Society for lifelong contributions to the technology of spaceflight. Early life and education Maxwell Hunter was born in Hollidaysburg, Pennsylvania and graduated from Washington and Jefferson College in that state with a degree in physics and mathematics. In 1944, he earned a Master's Degree in aeronautical engineering from the Massachusetts Institute of Technology (MIT). Accomplishments in aerospace After earning his MS from MIT, Hunter went to work for the Douglas Aircraft Company. He became their chief designer in aeronautics, working on modifications of the B-42 and B-43 bombers. Later he was promoted to chief engineer for space systems. In this position he oversaw the production of military missiles including the Honest John artillery rocket, the Nike antiaircraft missile, and the Sparrow air-to-air missile. Douglas Aircraft began work on the Thor, an early Intermediate Range Ballistic Missile (IRBM), in late 1955 and put Hunter in charge of that program. He assembled a small team of crack designers and brought the development to success in a short time. Thor became the basis of the McDonnell Douglas Delta rocket, whose descendants are still boosting payloads into Earth orbit today. After working for Douglas Aircraft from 1944 to 1961, Hunter joined the staff of the National Aeronautics and Space Council, a group that advised the U.S. president on space policy. Following several years in that position, he went back to the aerospace industry in 1965, spending over two decades with Lockheed Missiles and Space Company (LMSC). (LMSC was a division of Lockheed Corporation, which merged with Martin Marietta in 1995 to become Lockheed-Martin.) At LMSC, Hunter worked on a variety of projects including parts of the mammoth Strategic Defense Initiative. SDI gave him a chance at realizing a dream he had nurtured since the 1960s: the construction of a Single-stage-to-orbit (SSTO) vehicle. In 1984, Hunter proposed a vehicle he called the X-rocket, based on those earlier SSTO designs. The design was reviewed by LMSC's Astronautics Division (AD), which judged it worth
